**Molecular Mechanism and Rationale**
The aquaporin-4 (AQP4) water channel represents a critical component of the brain's clearance infrastructure, functioning as the primary facilitator of bulk fluid flow in the glymphatic system. AQP4 is predominantly expressed in astrocytic endfeet that ensheath cerebral blood vessels, where it forms orthogonal arrays of particles (OAPs) that create highly efficient water-conducting domains. The molecular organization of AQP4 involves two main isoforms: the
**Molecular Mechanism and Rationale**
The molecular mechanism underlying AQP4-mediated neuroinflammation centers on the critical role of aquaporin-4 water channels in maintaining blood-brain barrier (BBB) integrity and regulating astrocyte-mediated immune responses. AQP4, predominantly expressed in perivascular astrocyte end-feet, forms orthogonal arrays of particles (OAPs) that facilitate rapid water transport and maintain osmotic homeostasis. When AQP4 function becomes compromised, either thr
